I dreamt that I was in a large library and had somehow managed to get myself locked in overnight by mistake. I recall the dream starting as I realised what had happened and that I had to figure out what I was going to do until it opened again the next morning. I tried some of the doors but they were all locked and the only other observable exit was a passageway that inexplicably lead to what looked like a very dark forest (not sure why this was connected to a library...), but I decided against going through there as it looked too foreboding.
I spent much of my time there traversing the white walled corridors of the large library building, and at one point I heard the footsteps of a patrolling security guard so had to find somewhere to hide. I ran into another corridor where I saw a woman I remember from my old workplace. I started speaking to her casually and learned she worked at the library and was doing an overnight shift in an office there. She recognised me instantly and assumed I was working there as well (doing IT, as I do IRL) so I decided it was best to stick with her so that when the security guard saw us, he'd just think I was with her in the office and leave us alone. The dream ended somewhere around here.
